    I'm curious, has anyone confirmed the function of this card? If it is
indeed a stereo card, a very simple way to test it is to plug in a pair of
headphones and listen to the Music Construction Set GS demo (or the 
full version). The FTA's X-Mas Demo is also filled with nice examples
of stereo audio but not as blunt as Music Construction Set.

Here's an interesting blurb in the June 2002 'The Lamp', from Tony Diaz...

DOCTOR DESIGN SOUND CARD
""""""""""""""""""""""""
Has anyone ever heard of a Doctor Design sound card?  I have been browsing
a bunch of IIGS systems for sale and come across a couple of systems with
Doctor Design cards in their machines.  They have a headset jack and an
on/off switch, and it appears that they plug into the internal modular
sound connector.  Ever heard of this before?

I know a guy that works for Doctor Design, it's a for contract hardware
design facility - By the amount (or lack there of) I have surmised that
this card is some type of amp or signal stabilizer. To provide line level
perhaps. I've got a couple here. Seems they were popular in schools and
schools had headphones a lot. I've never hooked it up. He couldn't tell me
what it was because they made it under contract. (No secrets, just no
knowledge)

    I'd agree with Tony, there doesn't seem to be enough components on-board
to demultiplex the audio channels from the Ensoniq DOC. Though I'd still like
to know what exactly it does...

    As far as I knew, the only stereo cards were: SuperSonic, Audio Animator,
SonicBlaster, SoundMeister, Futuresound and GStereo. Is there a 7th?
